I sure hope Synology puts having MULTIPLE cache pools of a differet type, for a SINGLE storage pool's multiple Volumes, back on their development roadmap ASAP!!ĭon't believe me? Here are the links to official Synology articles on this obsecure yet to me very important topic. So, now I'm losing the expensive NVMe flash cache for my other volume(s), because I cannot afford to just add PHYSICAL storage bays with expensive EXTRA PHYSICAL HDD's on a whim to accomdite this DSM software change. SATA/NVME), is NO LONGER SUPPORTED).īasically, Synology's decision to KILL their best 2 caching features AND this card with these harsh DSM 7.1 limitations being UNABLE to use it for multi-volumes in a *SINGLE* mixed storage pool of SSD and NVME now, is really bad for my uses. Literally, what was working great in DSM 7.0.1 is now IMPOSSIBLE in DSM 7.1 (same storage-pool with multiple volumes cached by different cache types (e.g. It's not wrong: It's a HUGE design change. NOW: Synology has now posted this info in its official DSM 7.1 "SSD Cache release notes new for 7.1", to try and slow down confused customers like me, asking Synology's Tech Support what is going wrong. This is a HUGE problem for my config, which was fine in 7.0.1 but is now totally broken for my use in 7.1. Ouchies.Īlso Now, you get an ERROR that Cache Pools cannot contain both SATA-SSD and NVME-SSD. For clarity: NO: You CANNOT just use free space from your existing Storage Pool #1 to use for a Cache Pool #2 to keep using this comb-card. Now, Storage Pool #1 consisting of SATA SSD's and another consisting of the NVMe SSD's this combo-card uses, NOW must use separate PHYSICAL DRIVES to create a MULTIPLE Storage Pool #2 (not just Volume #2). MAJOR FUNCTIONALITY DELETED DSM 7.1 (using released Update-1), that directly adversely affects Synology's cache strategy and somewhat KILLS my config and this E10M20-T1 combo-card for me, as follows. With DSM 7.0.1, Synology's cache system and specifically in my case using this combo-card let you create two separate cache types for use in the same Storage Pool #1: One from SATA-SSD's for Cache #1 to use in Volume #1, and then Second Cache #2 from NVME-SSD's Combo Card Volume #2, for use on *SAME* Storage Pool. It *WAS* awesome while it lasted (DSM 7.01 was first to support E10M20-T1 in DS3617sx): Synology DSM 7.0.1 Update-3, worked great with the Synology 10Gb Ethernet and M.2 Adapter Card E10M20-T1, RJ-45 1 Port SSD/10G Combo-Card on my older DS3617xs. This post encourages discussion on the huge differences in these DSM Flash-Cache features now removed. DSM 6.2 through 6.2.4 Flash-Cache (SSD/NVME) worked great.ĭSM 7.1 now works entirely differently, removing many key features while adding just one feature.
